Fluxes
Solar Tabbing Fluxes
Solar Tabbing Fluxes are specialized soldering agents engineered to deliver clean, reliable electrical connections during photovoltaic cell tabbing and stringing. Indium Corporation supplies a range of Solar Tabbing Fluxes designed to promote excellent wetting and heat transfer while minimizing residue, helping manufacturers achieve strong bonds and consistent conductivity. Designed for high-throughput solar production, these fluxes from Indium Corporation support improved yield, long-term module reliability, and streamlined processing.

Product Overview
GS-1424
GS-1424 is a low-solids water-based formula that is ideal for use with open flux tank equipment.
GS-5414
GS-5414 is a very low solids halogen-free formula designed to leave cells and equipment dry and cosmetically clean after soldering.
GS-5415
GS-5415 is a low-solids, formula designed with evaporation control technology for heat flux pots and reduced crystallization properties.
GS-5415-1
GS-5415-1 is a fast-wetting, low-solids, alcohol-based formula with evaporation control technology for heat flux pots (that also works well in unheated pots), and contains reduced crystallization properties.
Features
Designed to perform on today’s high‑speed tabbing and stringing lines, Indium Corporation’s GS-suite of solar fluxes provide a wide process window and stable results across thermal conditions. Manufacturers will see the immediate benefit of fewer defects, reduced rework, and higher line yields—even as throughput increases.
Performance You Can Engineer With
- Optimized wetting behavior and controlled activation ensure uniform solder flow, strong metallurgical bonds, and low contact resistance—cell after cell, string after string.
Clean Chemistry, Reliable Outcomes
- Low‑residue, no‑clean formulations minimize post‑process concerns while maintaining excellent oxide removal and heat transfer.
Compliance Without Complexity
- Halogen‑free, RoHS‑ and REACH‑compliant formulations help manufacturers meet global regulatory requirements while maintaining process consistency.
Value Beyond the Process Step
- By improving consistency, reducing scrap, and supporting durable module performance, these fluxes contribute directly to lower cost per watt.
